No matter from any angle, Princess Caroline has nothing to do with the adjectives of greed and ruthlessness. However, when Xu Yi led the convoy to Thurwell City, he saw the top beauty who showed a series of passionate smiles and beautiful beauty next to Earl Samo, the smile on her face instantly became a little embarrassed.

"Hey, dear President Xu, you are finally here." Princess Caroline's smile became brighter after seeing Xu Yi, and she took the lead in saying hello to Xu Yi. "I have been waiting for you for this period of time."

Xu Yi calmed down a little when he remembered the previous incident and smiled and said, "His Princess has been waiting for a long time. However, it is a big deal to build a production base in Thurwell City. You must make complete preparations in advance before you can start, so it naturally takes time."

"Of course I understand this." Princess Caroline gave Xu Yi a pretty look. "It's just that I'm anxious and want to see you again."

Seeing the smile on the face of Count Samo on the side, Xu Yi coughed dryly, nodded, turned to Count Samo and said, "Sir, how are your preparations here?"

Earl Samo smiled slightly: "What? I haven't seen you for more than a year, don't you believe in my ability to do things?"

Xu Yi waved his hand quickly: "How dare you? I just want to know the specific situation and arrange the construction as soon as possible."

"Don't be busy for a while." Earl Samo's eyes crossed Xu Yi, landed on the long row of magic motorcycles behind Xu Yi, and nodded with satisfaction. "You just came today, take a break first, and start discussing work tomorrow. And Princess Caroline came here to wait for you a week in advance. I guess there was a lot to say to you."

Looking at Princess Caroline's sweet smile full of seduction, Xu Yi resisted the urge to roll his eyes at Earl Samo and turned around to call the convoy into the city together.

Compared to Batru, which is much smaller than Bonta City, the city of Thurwell, which is ranked first in the northeastern province, is obviously much bigger.

Not to mention anything else, the walls of Severe City alone are twice as high as those of Batru, and are much higher than those of Bonta City. And the thickness is even more amazing. When passing through the city gate, Xu Yi observed that the walls near the city gate were more than five meters thick. Although other places cannot be as thick as the city gate, they are definitely much thicker than those of Bonta City, which are made of only three layers of brick walls.

Seeing Xu Yi looking at the city wall, Earl Samo, who followed him into the city, smiled and said, "After all, the city of Thavier is close to the northern border, so you must be on guard against the Kingdom of Sach at any time, so it is appropriate to be thicker in the city wall."

Xu Yi nodded, but then he thought of a question.

"If you want to get close to the border, Bangta City is actually only more than 100 kilometers away from the southern border of the Kingdom. Why has the city wall never thickened?"

"Because the Kingdom of Rulson is an old friend of our Lampari Kingdom, the Kingdom of Rulson has been our loyal ally since the founding of the Kingdom of Rulson. It has never betrayed, so naturally there is no need to be too prepared for it." Count Samo explained.

Xu Yi nodded slightly, but felt a little dissatisfied.

Although the Rulson Kingdom has always been an ally of the Lampari Kingdom, there is only interest between countries. Old friends are not reliable.

In Xu Yi's view, the reason why Bangta City did not choose to strengthen the city wall was mostly because it had no money.

The finances of the Kingdom of Lampari were not abundant. In addition to ensuring the operation of the Kingdom, most of the limited financial resources were invested in defense against the Kingdom of Saks, so naturally there was no extra money to invest in defense in other places.

Even though Bangta City is now very rich, in the urban transformation project that Xu Yi and Earl Samo had never considered the transformation of the city wall.

Xu Yi came from the earth and never thought that he needed to widen and thicken the city walls to resist the enemy's problem, but Count Samo ignored it because of his inertia.

"Actually, the walls of your Bonta City are much higher and thicker than those of many cities in our Drake Principality." Princess Caroline, who was walking on the other side of Xu Yi, sighed quietly and looked at the walls of the city on the left and right of Thurwell. "As for the walls as thick as here, I'm afraid that I can't find the same ones in all the cities in our Drake Principality."

Xu Yi glanced at her and thought to himself that the reason why you, Drake's Principality, survived in the cracks between the Principality of Drake and the Kingdom of Lampari, was not relying on the city wall.

After a moment of heart movement, Xu Yi said to Princess Caroline: "Your Highness, if you have any ideas about renovating the city wall, I have a good plan here. As long as you transform the city wall according to this plan, I can guarantee that unless a magician of the level of magician takes action, there will be no problem with the city wall."

Princess Caroline and Count Samoy were both shocked and asked, "Really? What kind of city wall is this?"

Xu Yi smiled slightly, turned around and pointed to the road connecting Thurwell City outside the city gate.

"Your Highness Princess, Lord City Lord, I believe you all know that the road is mainly paved with concrete. You should have some understanding of the sturdiness of concrete now?"

Princess Caroline shook her head: "I have experienced the convenience of the road in your Lampari Kingdom. As for how the road is laid, it is not clear."

"Your Highness, if you, the Duchy of Drak, want to develop, then my first suggestion to you is to build roads." Xu Yi said seriously. "Only by solving the problem of road traffic and ensuring smooth and convenient transportation can the economy be more easily developed."

"Well, when I went to Bangta City last time, I saw countless carriages running back and forth on the roads of several cities around Bangta City. I was shocked by this spectacular scene. If our Duke of Drake also became like this, it would mean that our Duke of Destiny had developed." Princess Caroline said with emotion.

"There will definitely be this day." Xu Yi said.

"Thank you." Princess Caroline smiled sweetly at Xu Yi. "But President Xu, we seem to have moved the topic apart. Let me first tell me what the city wall you want to talk about that cannot even a great magician cannot destroy, right?"

Xu Yi did not answer this question immediately, but turned to Earl Samo and asked: "Master Lord, do you still have the impression of the reinforced concrete structure used in the Sandy River bank renovation project?"

Earl Samo's eyes lit up: "Of course I have an impression. What kind of structure do you mean... use that kind of structure to cast the city wall? But can that kind of structure support the city wall so high?"

"Of course." Xu Yi nodded. "Theoretically, as long as there is enough steel bars and cement, the reinforced concrete structure can even be erected to the sky."

Princess Caroline looked up at the sky in Severe City, and smiled: "President Xu, are you bragging, right? How could it be so high?"

"Don't believe it?" Xu Yi smiled and thought to himself that if you see the skyscrapers hundreds of meters high on the earth that soared into the sky, you may not believe your eyes.

And in fact, under Xu Yi's suggestion, President Cruise is leading the Amley Chamber of Commerce to conduct corresponding experiments. I believe that it will not take long before a real tall building in Bonta City that is far beyond the building level in the Synes continent.

"Okay, that's just theoretical. But since Xu Yi, since you said that, I think it would be fine to use this architecture to assume a high enough city wall." Earl Samo nodded. "But there is a very important question, how much does this city wall cost?"

Upon hearing this question, Princess Caroline stared at Xu Yi with beautiful eyes without blinking, her eyes full of concern.

"Master, if you build such a city wall, how much does it cost to build a city wall of 100 meters on average?" Xu Yi pointed to the wall of Severe City, which had been thrown away, and asked without answering a question.

"The words of the city of Thurwell..." Earl Samore pondered for a moment and replied: "If you put aside the labor, the cost per 100 meters is about 30,000 to 50,000 gold coins."

"So much?" Xu Yi was shocked.

Princess Caroline looked at Xu Yi for no reason: "Is there more?"

"Of course there are more." Xu Yi immediately said. "It costs 30,000 to 50,000 gold coins for one hundred meters. Then all the walls of Thurwell City will have to be at least more than ten kilometers. That's not three to five million gold coins? Isn't it too much?"

"No, the total cost of the city walls in Thurwell cost about six million gold coins, because you haven't counted the city gates and the arrow towers on the city walls." Earl Samo added. "Xu Yi, you think this cost is too high, so will the cost per 100 meters of the city wall of the reinforced concrete structure you mentioned is much less?"

Looking at Princess Caroline's expression of disbelief but extremely expectant, Xu Yi smiled slightly: "Of course. The main body of the reinforced concrete structure is steel bars, and the cost of concrete is much less. According to current estimates, if a reinforced concrete city wall that is three meters thick, five meters high and one hundred meters long is built, the total price should not exceed 10,000 gold coins."

"So cheap?" Earl Samo and Princess Caroline both looked disbelief.

But after a moment, the two of them changed their expressions of surprise.

Because both of them knew very well, Xu Yi would never joke with them like this about such things.

Princess Caroline blinked her big eyes and asked again: "President Xu, do you have to buy all the reinforced concrete you mentioned from your Xinfei Chamber of Commerce?"

Xu Yi smiled and said, "Or what do you think I'm doing to promote reinforced concrete structure walls so hard?"

Princess Caroline glanced at Xu Yi and snorted softly: "But you can't let us run far to Bangta City to buy it, right?"

"You're right, so after our Chamber of Commerce came to Thurwell City, the first one to build was a cement plant and then a steel mill."
